I use Peco electrofrog; they have the same problem when their points get dirty and need the same treatment as below. <br /> <br />Make a bellcrank linkage from the throwbar to an SPDT under-table microswitch with music wire or brass rod so the microswitch duplicates the switching of the points. Make sure to adjust so that the microswitch operates when the points are at mid travel. There are several other methods as well if the microswitch is unworkable for you. Cabbose Industries makes a 12 foot high N scale ground throw with contacts, but I believe these are low current and may need a relay switch to meet locomotive current draw.
